Hi, This can be seen as a general question or a question related to the assessed lab, but I was wondering about the appropriate uses of the @Ov*r*i*e annotation. Should we use @Ov*r*i*e every time we try to override a method to catch errors, or is that unnecessary for some of the simpler methods? In other words, how do you determine when we should use the annotation before we override a method? Also, are there any other annotations we should pay attention to, apart from @Ov*r*i*e? Maybe I have terrible memory, but I don't recall us covering other relevant annotations in the unit so far. Thank you so much!
